HBO's successful sci-fi drama “Westworld” has been renewed for a second season. HBO

HBO has released the official marketing art for its upcoming sci-fi drama called “Westworld,” which features an android “host” clinging on to a round beam with the show’s double “W” logo on the background.

It carries the new tagline “Every Hero Has a Code,” and Entertainment Weekly reported that it’s because the protagonists of this updated version of Michael Crichton’s 1973 film are actually robots, while the humans who go to the Western theme park seem to be devoid of morality.

The new trailer released by the network shows how the robotic “hosts” deal with humans’ deception and shocking indulgences. The trailer shows glimpses of how humans run amok in Westworld, with violent shootings, sex scenes, a milk-drinking cowboy with holes in a body and several dead bodies scattered all over the street.

Evan Rachel Wood’s protagonist Dolores Abernathy seems to be right smack at the middle of the controversies hounding the theme park, but she voices over in the trailer: “Sometimes I feel like the world out there is calling me.”

Dolores is deemed as an anomaly in the world created by Anthony Hopkins’ Dr. Robert Ford, and the trailer ends with her questioning him if they are friends. “I wouldn’t say that at all,” he answers in the clip.

Because the show will feature a rape scene in its pilot episode, “Westworld” already drew in some criticisms. But Lisa Joy, one of the show creators, told the L.A. Times that it was important for them to incorporate sexual violence because it has “sadly been a fact of human history since the beginning of human history.”

“Sexual violence, not only for me but for everybody on our team, is an issue that we take seriously. It’s extraordinarily disturbing and horrifying. In its portrayal we really endeavored for it to not be about the fetishization of those acts,” she explained. “It is about exploring the crime and establishing the crime, and the torment of the characters within this story. And exploring their stories, hopefully with dignity and depth.”

“Westworld” will be released on HBO on Sunday, Oct. 2, at 9 p.m.
